Floral Phenotypes of Strains Used in This Study.
Landsberg erecta (A), ap1-1 (B), ap2-2 (C), ap3-3 (D), pi-1 (E), and ag-3 (F) mature flowers are shown. The diagram depicts the expected changes in levels of organ-specific transcripts in the floral mutants compared with wild-type plants. (−), absent; (↑), upregulated; (↓), downregulated; (?), questionable.
